The Virginia Department of Transportation is undertaking aconstruction project to widen a large section of interstate, highway near Washington, DC, which includes the construc-tion of a number of new bridges, interchanges, and over-passes. The first step in the project is the appointment of a project manger and the development of a project team, someof which will be departmental employees and others will beprivate consultants and operatives. The team for a project thissize also requires a large support staff with varying technicalskills. Once the team is selected and the staff is in place the first task is to select a primary contractor to manage and over-see the actual construction. The following activities are stan-dard for the planning and scheduling of this process: Construct the CPM/PERT network for this project and de-termine the project schedule. Identify the critical path and determine the expected project duration time and variance.Determine the probability that the team and…

We are the project manager for an IT project in our company. We identified the following top-level project tasks and estimated durations to standup a small test lab for the project: Identify test lab building/space requirements and possible locations(8days) Select best location for lab (1day) Once the best location is selected, immediately start the next two tasks: Prepare lab space with power and cabling (3days) Identify/procure required specialized test lab hardware/software(5) Once the lab space is prepared, install/check out available infrastructure hardware/software(1day). Once the specialized software/hardware is received and the infrastructure hardware/software is installed/checked out, install/checkout specialized software/hardware (2days) Once all tasks are completed, conduct the final inspection (1 day). Let's create a PERT/CPM chart for this project and identify the overall project duration and critical path.
